Question 417549


you are correct............


For the profit percentage, the initial cost is 10,000€,

that's 200€ each , so an 80% increase would be 360€ each.

He sells 40%, or 30 items at 360€ = 10,800€
He sells 60%, or 20 items at 171€ =  3,420€  total = 14,220€

So the profit percent would be 14,220 - 10,000 = 4220/10,000=0.422

or 42.2%
